Does it sound like I may have OCD or some sort of mental problem?

Having dealt w/someone w/OCD you have some of the symptoms. My first suggestion would be to contact your primary care physician and have a thorough examination/blood work up/the whole deal. Eliminate the possibility ofany physical problems. Next I would see a therapist. Your dr. can recommend one. Meanwhile, start journaling. You'll be surprised at how much will come out of this. Simply start writing, almost to the point of not deliberately thinking too much about what you are writing. Let out your true feelings. Set it aside without reading what you wrote. The next day do the same, for a wk and then go back and read your writings. Something may just pop out at you and give you a clue as to why you do not allow yourself to follow through. Keep journaling. Your dr. may even suggest a low dosage of an antidepressent. Be open with your thinking. You do not have a mental problem. This just sounds like a bump in the road - Good Luck!
